Care

Hoya pubicalyxlike bright, indirect light-- such as light that is filtered through a sheer curtain or gets diffused through a room. So be sure not to place your hoya somewhere that receives lots of intense, harsh sunlight. Although their leaves might feel leathery and thick and they can tolerate a few hours with direct sunlight, these plants can show signs of damage if they get too much.

If you are having trouble getting your Hoya to bloom, it's usually because it's getting too little light and is not being allowed to dry up enough between waterings. Although most hoyas can handle lower light and will continue to grow and produce green leaves, this may be a factor in it not producing any flowers.

These plants actually thrive in fairly tight pots, so don't plant yours in a pot that's too big and always use one with drainage holes.

Less is more when it comes to watering - you can allow the soil to dry out completely in between waterings.
